Wonderful in its time a decade and more ago, played it thru ~half a dozen times, but for PC players it is very much inferior to subsequent titles in the series. It still has great meme value via Michael Mando's wonderful portrayal of villain Vaas Montenegro—but that's about all it has these days, so just watch a few memes on YouTube.

For anyone wanting to try FC series, my current preference sequence is:
FC5 with Resistance mod
FC6
FC5 New Dawn
FC4
FC4 Primal [if you like melee]
FC4 Yetis DLC
